[FIX] stock_valuation_fifo_lot

This commit fixes the incorrect stock_valuation_layer values for deliveries when the product was received before this module was installed.
The issue occurs because the old stock_valuation_layer records do not have lot_ids values, which leads to incorrect valuation during the delivery process.
